Abstract
Various aspects provide for mitigating voltage droop associated with a microprocessor (e.g., by controlling a clock associated with the microprocessor). For example, a system can include a microprocessor and a controller. The microprocessor can receive a clock provided by a clock buffer. The controller can control frequency of the clock provided by the clock buffer based on a voltage associated with the microprocessor. In an aspect, the controller can reduce the frequency of the clock in response to a determination that the voltage satisfies a defined criterion. Additionally, the controller can incrementally increase the frequency of the clock in response to another determination that the voltage satisfies another defined criterion after satisfying the defined criterion.
